Supply chain finance starts from the whole industrial supply chain, through cooperation with core enterprises, taking core enterprises as the starting point, effectively injecting funds into upstream and downstream supporting SMEs that are in a relatively weak position through comprehensive credit, solving the problems of financing difficulties of SMEs and imbalance of the supply chain; at the same time, integrating bank credit into the purchasing and selling behaviors of upstream and downstream enterprises, enhancing their commercial credit, and promoting the establishment of long-term strategic synergistic relationship between SMEs and core enterprises, and enhancing the competitiveness of the supply chain. At the same time, it integrates bank credit into the purchasing and selling behaviors of upstream and downstream enterprises, strengthens their commercial credit, promotes the establishment of long-term strategic synergistic relationship between SMEs and core enterprises, and enhances the competitiveness of supply chains.

As the world steps into the era of information economy, e-commerce, which is characterized by the close integration of information high technology with economy and management, is developing vigorously. The integration of e-commerce and supply chain has become an inevitable trend, and the e-commerce-based supply chain system has stronger financing needs compared with the traditional supply chain. Small and medium-sized enterprises (SMEs) are the main financing demand customers in supply chain finance. Due to their small scale and small assets, they are often unable to obtain financing from commercial banks through traditional asset collateralization, which results in difficulties in financing for SMEs and insufficient liquidity, and greatly restricts the development of SMEs in China. Although traditional supply chain finance was born to help SMEs in the supply chain to finance, facing the e-commerce supply chain system with a huge number of small and micro enterprises, the traditional supply chain finance model has been unable to fully meet the demand.

Supply chain finance starts from a new perspective and proposes a new e-commerce supply chain finance model based on the positioning of e-commerce's role in the supply chain system. The e-commerce itself only provides a trading platform for upstream and downstream suppliers, and it does not operate a warehousing and logistics system of its own, and there are no cash transactions such as accounts receivable with upstream suppliers. In this e-commerce supply chain system, the e-commerce platform has a relatively small degree of control over the logistics and capital flow, but the e-commerce company has control over the information flow, and all the transactions in the supply chain system are carried out on the e-commerce platform, and the e-commerce company can analyze the financing risks based on a large amount of transaction data.

This kind of supply chain financing is a more innovative supply chain financing model, in which e-commerce replaces the position of banks in providing financing services in traditional supply chain finance and, with data and the Internet as the core, establishes a rich database of suppliers and credit records, and provides credit loans to small and medium-sized enterprises (SMEs) on its platform by making use of the huge customer resources, massive data on the transaction behaviors of customers, and information technology processing means such as cloud computing. By integrating the data and credit formed in the process of e-commerce, the e-commerce company solves the problems of information asymmetry and complicated processes that exist in the traditional financial industry for individual and small business loans, and realizes good risk control and capital return.

The development of Internet supply chain finance is not only the trend of supply chain finance development in the IT era, at the same time, it also creates another way for small and micro-enterprises to solve financing problems. Internet supply chain finance can not only improve the liquidity of funds in the supply chain system with e-commerce as the core, but also help to improve the relationship between upstream and downstream supply chain, integrate and optimize the capital flow, logistics and information flow, enhance the operational efficiency and value of the entire supply chain, and facilitate the collaborative management of e-commerce enterprises' business operation and innovation to achieve win-win situation for all parties.
